Description of key information
No study was conducted on the fractionned oil iself, as not relevant for an UVCB.
The test item is a natural complex substance (NCS). It is a mixture of several constituents, but seven of them represent more than 90% of that mixture.
Literature provided data for these 7 major components :
| Constituent names | CAS nr | Vapor pressure (mm Hg at 25°C) | source |
| linalool (ca 60%) | 78 -70 -6 | 0.16 | HSDB |
| camphor (ca 13%) | 76 -22 -2 | 0.65 | HSDB |
| cis ocimene / beta ocimene (ca 7%) | 3338-55-4 | 2.68 | EPI suite v4.11 |
| terpinene-4-ol (ca 3%) | 562-74-3 | 0.04 | HSDB |
| limonene (ca 1%) | 5989-27-5 | 1.98 | HSDB |
| linalyle acetate (ca 1%) | 115-95-7 | 0.111 | HSDB |
| eucalyptol (ca 1.5%) | 470-82-6 | 1.90 |
HSDB |
Minimal vapor pressure is 0.04 mmHg and maximal vapor pressure is 2.68 mmHg at 25°C.
The range reported above should be used with caution because these constituants are not represented at the same content.
Key value for chemical safety assessment
Additional information
As no CSA is required for the tonnage band of concern, no key value was retained (nor calculated weighted VP nor worst-case).
